The Go path is used to resolve import statements.
It is implemented by and documented in the go/build package.

The GOPATH environment variable lists places to look for Go code.
On Unix, the value is a colon-separated string.
On Windows, the value is a semicolon-separated string.
On Plan 9, the value is a list.

If the environment variable is unset, GOPATH defaults
to a subdirectory named "go" in the user's home directory
($HOME/go on Unix, %USERPROFILE%\go on Windows),
unless that directory holds a Go distribution.
Run "go env GOPATH" to see the current GOPATH.

See https://golang.org/wiki/SettingGOPATH to set a custom GOPATH.
